Answers :

What codes are you getting? check all spark plug wires as a start. pull one of the spark plug wires off while car is running. if you notice an improvement in idleling then it may be a coil pack. each spark plug has a coil pack if only one goes out it will be a rough running car. i had to replace 2. sometimes they just go out without warning. the other thing would be to change the spark plugs and wires. if you have over 75,000 miles on the car then i would replace. todays spark plugs are good up to and over 50,000 miles. simple fix. the only hard part is the 3 plugs on the firewall. little room to get them but it will take about 1-2 hours just for those back 3 plugs unless you have the right tools. then if all this fails i would check the egr sensor......oh even easier first check all your vacuum hoses it only takes 1 to screw up your performance. vacuum hose is a cheap fix. good luck and email me back if i helped or not. i like trouble shooting. my grand prix purrs like a kitten most of the time..
Sounds like a large vacuum leak. Possible hose off, intake gasket blown, etc. Listen for any vacuum hissing sounds from a leak somewhere.
